Change autocxx-build version to 0.27.0

The minimal Rust version for the bindings is `1.74.0`.
Recently, the `home` [^1] package raised its minimal supported rust version
to `v1.81.0` which breaks our min-rust requirement.

Before this commit, `lief-ffigen` was depending on this package via the
following dependency tree:

```
lief-ffigen v0.17.0 (/src/api/rust/cargo/lief-ffigen)
├── autocxx-build v0.26.0
│   ├── autocxx-engine v0.26.0
│   │   ├── autocxx-bindgen v0.65.1
│   │   │   └── which v4.4.2
│   │   │       └── home v0.5.11
```

It turns out that `which` is no longer a dependency of `autocxx-bindgen`
since this commit: c03964c0257b03ad4762b57f3ffb96d32d49c0ce[^2].

This commit is part of the `0.27.0` release of `autocxx-engine`.
